INHALER.

To all whom it may concern:

Be it known that I, FRANK C. DORMENT, a citizen of the United States,residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented a certain new and useful Improvement in Inhalers, of which thefollowing is a full, clear, and exact description.

The present invention relates to inhalers of the small or portable typeembodying a receptacle adapted to contain a desired medicinal material,which receptacle has suitable outlet for application by the user to themouth or nose, and by respiration air is drawn through the receptacleimpregnated with the medicinal material and passes to the nose passages,throat and lungs of the user.

Among the objects sought to be accomplished is to provide an inhaler ofsuch construction that the device is sanitary and use does not vitiatethe contents of the inhaler.

A further object is to provide a construction by which the device isrendered substantially non-leakable so that it may be carriedin thepocket of the user, and the contents will not be discharged when thedevice is carried in other than an upright position. v

A further object is to provide a structure wherein the user byrespiration forces air through the liquid within the receptacle wherebythe air becomes charged with vapor, and further to provide aconstruction for the purpose which will be sightly in appearance but soconstructed as to permit of low cost of manufacture.

Other objects will appear as the description proceeds, and generally,the invention may be said to comprise the elements and combinationsthereof set forth in the accompanying claims.

Reference should be had to the accompanying drawings forming a part ofthis invention, in which Figure 1 is a sectional elevation of thedevice; Fig. 2 is an elevation partly in section of the device; and Fig.3 is a section on the line 3-3 of Fig. 1.

Referring to the drawings, 1 indicates a container or receptacle whichis hollow, and at its upper portion has an opening through which extendsa tube 2. This tube projects upon the outside of the receptacle andthere is a go-odl portion of the tube which ex tends within thereceptacle,

Specification of Letters Patent.

Patented Sept. 2, 1919.

Application filed December 26, 1918. Serial No. 268,251.

The end of the tube 2 which is upon the outside of the receptacle isadapted to re ceive an end piece 3 which preferably is formed to fitover the tube 2, and has a central passage 3*. The end member 3 is ofsuitable form so that the device may be applied to' the mouth of theuser or to the nostril.

The lower portion of the container is closed by means of a head 4. Thishead is provided with an extending flange l" which engages with thewalls at the lower end of the receptacle 1, and the head 4 is secured tothe receptacle 1 in a position indicated in the drawings in any suitablemanner, as by a soldering or sweatingproccss. Within the receptaclethere is a tubular member 5. This tubular member is open at its lowerend, and cooperates with a boss or extension 4" formed upon the innerside of the head 4:. The tubular member 5 is secured to the boss 1 inany desired manner, as by a soldering orsweating process. The tubularmember is, adjacent its lower portion, provided with one or moreopenings, such as indicated at 5*. Through the boss 4 there is anopening through which extends a short tube 6. The tube 6 as shown in thedrawing extends up into the tubular member 5. The tube is secured to theboss 4 in any desired manner, as by a soldering or sweating' process. I

In operation, when the part 3 is applied to the mouth or nostril of auser, the inhalation of the user draws air through the tube 6, which airpasses through liquid contained within the receptacle 1, through theopenings 5, through the tube 2, and to the mouth or nostril of the user.It will thus be seen that the air is forced through the liquid and inpassing through the liquid becomes saturated with vapor of the liquid,and in this condition passes to the user.

It will be apparent that when the receptacle is carried in its uprightor vertical position as shown in the drawing, the liquid is so heldwithin the container as to be nonleakable. If the receptacle be invertedwith respect to the position shown in the drawing, it will be seen thatthe liquid will in part collect in the portion of the receptacle 1adjacent the tube 2. The tube 2 is of such length that the liquid willnot find exit through that tube. That portion of the liquid whichnormally lies within the tubular member 5, w ill fiow to the closed bepractically negligible.

One very great advantage of the construction as has just beendescribed,lies in the fact that the device may be very inexpensively manufactured.The receptacle 1 may be formed by a drawing process from a flat blank.The part4 may also be formed as a stamping. The tubular member 5 may bedrawn from a flat blank. The tubes 2 and 6 of proper sizes for use inthisdevice are articles of commerce which may be obtained on the openmarket and require no special "processes in their manufacture. In fillinthe device, the part3 isremoved and a su cient quantity of the medicinalliquid which it is desired to use is poured through the tube 2. It willbe obvious that changes in. the details of construction may be madewithout departing from the spirit of this invention. Having described myinvention, I claim: 1.
